This is the seventh in a series of biennial interdisciplinary conferences on consciousness held in Tucson in even-numbered years since 1994. The “Tucson conferences” have helped to catalyze the recent development of scientific research on all aspects of the problem of consciousness.

The Tucson conferences stress interdisciplinary exploration, bringing together perspectives from philosophy, neuroscience, psychology, cognitive science, computer science, physics, biology, anthropology, contemplative traditions, the arts, medicine, and other areas. A continuing focus of the conference is the integration of the first-person and third-person perspectives on the phenomena of the mind.

One may ask: “How much closer are we in moving toward a science of consciousness?” Are we there yet? Or, as in the “Myth of Sisyphus” are we farther away as new, confusing details about brain activities are discovered without revealing the nature of consciousness? We do not yet understand consciousness, but it is fair to say that, at the very least, we understand the problem

far better.

The dictionary defines science as: “The observation, identification, description, experimental investigation, and theoretical explanation of
phenomena”. Among these, consciousness has clearly been identified, described, experimentally investigated and elicited theoretical explanations (though disagreements certainly exist among various approaches in each category). Regarding observation, consciousness cannot be directly measured or observed by third persons, but first person accounts are prevalent. Thus it appears that,
yes indeed, there may now be a science of consciousness.

Some highlights of the scheduled program include the following:

The plenary program is now complete: the Keynote talk on Wednesday, April 5 will be given by Giulio Tononi M.D., Ph.D. of the Center for Sleep and Consciousness at the University of Wisconsin. Professor Tononi has put forth the "Information integration theory" of consciousness, building upon and quantifying earlier work with Gerald Edelman on the Dynamic Core hypothesis. Tononi and colleagues are pursuing this approach using a variety of experimental and theoretical modalities. Sleep is another key interest of Tononi and his group who have recently shown significant differences in cortical connectivity in sleep versus wakeful consciousness.

His keynote talk should complement both the opening Plenary session on Neural correlates of consciousness (Walter Freeman, Ralph Freeman, Hakwan Lau), and the "Dream Debate" (Alan Hobson and Mark Solms).

Temple Grandin, Ph.D., is the most accomplished autistic person in the world. She is the author of best-selling “Thinking in pictures and other reports from my life with autism”, “Emergence: Labeled autistic”, “Animals in translation” and other books, videos and DVDs, and an accomplished lecturer who has been featured on major television programs and magazines.

Dr Grandin was one of the “challenged” people featured in Oliver Sacks’ book. “Anthropologist from Mars”. Sacks described Grandin’s first book “Emergence: Labeled autistic” as “Unprecedented because there had never before been an 'inside narrative' of autism; unthinkable because it had been medical dogma for forty years or more that there was no 'inside,' no inner life, in the autistic. . .extraordinary because of its extreme (and strange) directness and clarity. Temple Grandin's voice came from a place which had never had a voice. . .and she spoke not only for herself, but for thousands of others. . .”

Seeming to have unique insight into the conscious minds of non-verbal animals, Grandin is also known for her work in handling and humane slaughter of cattle and other animals. She is an Associate Professor at Colorado State University, and her websites are http://templegrandin.com/templehome.html and http://www.grandin.com/ The abstract for her talk (on Saturday April 8) "I think in pictures instead of language" can be found here.

Dream debate: The significance of dreams and the role of Freud and the unconscious will be the topic of a formal debate between psychiatrists J. Allan Hobson from Harvard Medical School, and Mark Solms from London’s St. Bartholomew's and Royal School of Medicine. Hobson maintains that dreams are noise whose bizarre character stems from the same neurochemistry responsible for hallucinations, and that Freud is irrelevant. Solms points to new imaging results showing significant activity in brain regions underlying emotional drives and reward during REM sleep. The debate will reprise Solms’ 2004 Scientific American piece "Freud returns" and Hobson’s response "Like a bad dream". This should be fun.

The eminent cognitive science pioneer Douglas Hofstadter from Indiana University will also speak at Tucson for the first time. He is Professor of Cognitive Science, Computer Science, History, Philosophy, Comparative Literature, and Psychology. Professor Hofstadter has received (among other awards) a Pulitzer Prize, Guggenheim fellowship and a 1980 American Book Award for "Gödel, Escher, Bach: An eternal golden braid". He has also written "Metamagical themas: Questing for the essence of mind and pattern", and (with Daniel Dennett) "The Mind's I: Fantasies and reflections on self and soul". Professor Hofstadter is now writing a book about consciousness and will speak to us about his new ideas.

At least to date, and as far as we know, consciousness exists only in biological brains, raising the question of whether biology - life itself - holds the key to its understanding. Author/physicist and Templeton award winner Paul Davies from MacQuarie University in Australia will speak on the nature and origin of life. Paul is the author of numerous scientific articles and popular books including"The fifth miracle: The search for the origin and meaning of life", "Mind of God: The scientific basis for a rational world", "About time: Einstein’s unfinished revolution", and many others.

And the always to-the-point UC Berkeley’s John Searle, Mills Professor of Philosophy and Language will speak on "Dualism revisited", describing his latest views on status of modern approaches to the understanding of consciousness. Originator of the famous “Chinese room argument”, Searle is the author of "Mind: A brief introduction", "The mystery of consciousness", and "The rediscovery of the mind".

In the Meditation session, Antoine Lutz and John Dunne will discuss their findings (e.g. their PNAS paper) on EEG in Tibetan monk meditators vs control meditators. They found in the Tibetans the highest amplitude gamma synchrony ever reported!

Plenary sessions will be devoted to topics including the neural-level correlate of consciousness, consciousness and chronic vegetative states, consciousness and emotion, Freud and dream science, cognitive architectures, visual fading, virtual reality, meditation and brain states and self-representational theories of consciousness and the physics of life.

The conference will also feature many concurrent and poster sessions on various topics including mainstream philosophy, brain imaging techniques, quantum theories of consciousness, unconscious processes and assorted first person experiential approaches.

Pre-conference workshops will provide in-depth tutorials in many different areas.

As always the personal interactions among the highly interdisciplinary attendees will be encouraged by social events including an opening reception, evening banquet at the beautiful Arizona-Sonora Desert Museum and ever-popular Poetry Slam and Zombie Blues renditions. The conference will conclude with the traditional "End-of-Consciousness” party.
